H-index is a main indicator of research impact based on citation measurement ,is it a perfect index to evaluate the impact of a researcher's publication output
Many authors consider it not only the safest way to measure researchers' scientific quality, but also a good tool for assessing regular production and forecasting its future scientific performance, as it combines productivity and impact.
The H index of a researcher is defined as the number of articles published by the researcher, whose citations are greater than or equal to that number. For example, when we say that the H index of a researcher is ten, it means that he has at least ten articles published, each with at least ten citations. The greater the number of articles of great interest published by the researcher, the greater the number of citations achieved, and the greater his H index, reflecting the academic and scientific quality of the researcher and his production capacity. However, only the total number of articles, for example, may hide the lack of relevance of each text in isolation. We can thus say that the H index is the result of the balance between the number of publications and the number of citations.
According to my opinion it is not well enough to judge the quality of researchers' activities.
Not always and as condition for it must be H-index as good indicator for this case, but I saw more the articles which have more citation and it scientifically less benefit. So, I think not reflect the quality of reseecher.

h-index reflects both the number of publications and the number of citations.the h-index does not account for the typical number of citations in different fields. It has been stated that citation behavior in general is affected by field-dependent factors.SO H index reflects the quality of researchers.
The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications, so I think it reflects the quality of researchers.
Thank you for raising the good question in discussion. There are different way how the quality of researcher/academic is assessed. Total citation, H-index and i10- index in academics are all considered important. Furhter discipline wise, article published in the high impact factor also makes some sense.
Any way H index covers all the citation irrespective of quality of article or journal which has given some relief for those academic who could not publish in the high impact journal. So I think H - index is one of the best alternative way to measure the quality of author.
Please also look on the previous discussions about different in total citation, H-index and i10 index.
h index corresponds to a scientist's h of his/her N papers that have been cited at least h times each, while the rest of the N papers have less than h citations each.
I think h index is not enough indicator to evaluate the quality of researchers. However, it will be better to consider other indicators with it, such as i10 index and G-index.
i10 index refers to the number of paper with 10 or more citations.
For the citations received and given a number of papers ranked in a decreasing order according to the citations received till now, the G-index is the biggest number such that the top G articles received (altogether) at least G2 (G square) citations.
How much time does it take to judge the "quality" of any human endeavor? Shouldn't the evaluation of research, that is, of any one research product, be best evaluated over time to assess its "quality and durability over time'?
I think in addition to the H index if the researcher is having good research score then both can describe the quality of research, research score is well describe by the research articles published by the researcher
I do not think so because it depends on the number of citation of research from journals that thrive within Thompson Reuter and others .. This makes research published in other languages and publishing houses not covered by this assessmentand therefore unable to get H-index
The advantage of the h-index is that it combines an assessment of both quantity (number of papers) and quality (impact, or citations to these papers) (Glänzel, 2006). An academic cannot have a high h-index without publishing a substantial number of papers. However, this is not enough. These papers need to be cited by other academics in order to count for the h-index.
As such the h-index is said to be preferable over the total number of citations as it corrects for one hit wonders, i.e. academics who might have authored (or co-authored) one or a limited number of highly-cited papers, but have not shown a sustained and durable academic performance. It is also preferable over the number of papers as it corrects for papers that are not cited. Hence the h-index favours academics that publish a continuous stream of papers with lasting and above-average impact. (Bornmann & Daniel, forth).
H index reflects highest number of publications that received H citations. More the citation more is the H index.
If we consider that the research is more scholarly because the citation are more, then H index reflects the quality of research. However it may not be true always.
The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications.
H-index is one of the indicators of research impact based on citation measurement. But it is not the only index to evaluate the impact of a researcher's output. Some of the other indicators for judging the output of a researcher are:
1. Number of publications in Web of Science/SCI/Scopus indexed journals having high impact factor.
2. Number of Patents filed, published, granted and licensed
3. Amount of research funding earned by a researcher from Projects.
Based on the: As first-author ratio to all papers published, h index in Scopus, the total impact factor of the journals, the high impact factor of the paper, No. of patents, granted and research funding.
